compressor outlet tem-
perature�
Fd Temperature protection
for system has tripped
as a result of high/low
ambient temperature� 1� Check sensor for ambient temperature�
2� Check if ambient temperature is outside permitted operating
temperature (lower than -1 or higher than 65°C during cooling,
lower than -25 or higher than 45°C during heating)�

ter pump or flow switch� 1� Check water flow in water pump�
2� Check connection of flow switch� If there is enough water
flowing in the system, check whether the flow switch works�
Replace flow switch, if necessary�
